ISO 18000
ISO 18000 is an international standard that describes the protocols used on the contactless chipcard interface ( CCI ) of RFID.
The ISO 18000 standard covers the transmission of identification information, phase jitter modulation( PJM) and the air interface in various RFID applications at the RFID frequencies of 125 kHz, 13.56 MHz and 2.54 GHz. In addition, the frequency range between 850 MHz and 950 MHz for UHF tags from EPCglobal. The ISO 18000 standard also covers the far- field coupling of contactless smart cards, which can be used to bridge distances of more than 3 meters.
